摘要
为探究不同通透性保鲜膜对香菇保鲜效果的影响,以采后新鲜香菇为原料,分别以市售低通透性保鲜膜(旭包鲜PVDC保鲜膜)、中通透性保鲜膜(枫康PE保鲜膜)、高通透性保鲜膜(七彩阳光PVC保鲜膜)为包装材料对香菇进行包装,将其置于4℃环境中进行贮藏试验。结果表明,与PVC保鲜膜相比,PE保鲜膜和PVDC保鲜膜均显著降低了香菇失重率(P<0.05);PE保鲜膜显著抑制香菇的呼吸作用,延缓香菇中VC含量与多糖含量的降低,抑制细胞膜渗透率、丙二醛含量及内源性甲醛含量的升高(P<0.05);3种不同通透性保鲜膜以PE保鲜膜保鲜效果最佳。
To explore the effects of different permeability films on fresh-keeping of Lentinus edodes,with the fresh L. edodes as experiment materials,the storage experiments were conducted under the 4℃ environment with low permeability film( PVDC),medium permeability film( PE) and high permeability film( PVC) respectively. The results showed that,compared with PVC film,PE film and PVDC film could significantly reduce the weight loss rate of L. edodes( P < 0. 05); PE film significantly inhibited the respiration of L.edodes,delayed the reduction of VC content and polysaccharide content in L. edodes,and inhibited the cell membrane permeability,malondialdehyde content and endogenous formaldehyde content increasing( P <0. 05). The PE film had the best fresh-keeping effect among the 3 different permeability films.
